Mbh 6.59.2h

Behold, I will soon throw Bhishma down from his car, and Drona also in battle, with all their followers. There is none in the Kuru host, O thou of the Satwata race, who is able to escape my angry self. Therefore, taking up my fierce discus, I will slay Bhishma of high vows. And slaying in battle those two foremost of car-warriors, viz., Bhishma along with his followers and Drona also, O grandson of Sini, I will gladden Dhananjaya, and the king, and Bhima, and the twin Aswins. And slaying all the sons of Dhritarashtra and all those foremost of kings who have embraced their side, I will joyfully furnish king Ajatasatru with a kingdom today.’ Saying this, Vasudeva’s son, abandoning (the reins of) the steeds, jumped down from the car, whirling with his (right) arm his discus of beautiful nave with edge sharp as a razor, effulgent as the sun and possessed of force equal to that of a thousand bolts of heaven. And making the earth tremble under his tread, the high-souled Krishna rushed impetuously towards Bhishma. And that grinder of foes, the younger brother of the chief of the gods, excited with wrath, rushed towards Bhishma staying in the midst of his troops, like a lion from desire of slaying upon a prince of elephants blinded with fury and staying proudly for the attack. And the end of his yellow garments waving in the air looked like a cloud charged with lightning in the sky. And that lotus of a discus called Sudarsana, having for its stalk the beautiful arm of Saurin, looked as beautiful as the primeval lotus, bright as the morning sun, which sprung from the navel of Narayana. And Krishna’s wrath was the morning sun that caused that lotus to blow. And the beautiful leaves of that lotus were as sharp as the edge of a razor. And Krishna’s body was the beautiful lake, and his (right) arm the stalk springing therefrom, upon which that lotus shone.
